Hi all.
for tune-up the HITACHI CARB. 240Z is necessary :
chek oil level inside carburetor dome ( level between min and max line )
disconnect front and rear carb.
For disconnect the 2� carb is necessary:
loose the screw A ( FAST IDLE MIN RPM )
loose balance screw B
disconnect CHOKE CABLE (C) for front carburetor and other cable for 2�carburetor.
the small arm/lever D don't touch the balance connection
remove the small arm connection E ( the foot accelerator inside the car not connectet at carburetor )
closed the NUT under the front and rear carb. and after open the nut under front and rear carburetor.
open about 2 turn around (+ or - 1.95 turn)
see table chart ambient temperature 32�C and altitude 20-50m over sea level.
set/tune the mim RPM between 600 -700 RPM for 1� carburetor
use FLOWMETER on front carburetor for 1-2 seconds max ( see the level of ball in the scale of flowmeter)
connect the 2� carb at 1� carb with FAST IDLE MIN RPM (A) and BALANCE SCREW (B) and ARM/LEVER (D) and connect (E)
tune the 2� carburetor with throttle screw.
rotate the screw in one direction on opposite direction.
connect the FLOWMETER on 2� carburetor
the ball inside the scale of flow meter have the same value of 1� carburetor
